Pirate: I Just Became a Celestial Dragon, and My Father Asked Me to Kill Someone.

[No system + Navy style + Celestial Dragons + Fantasy beast species + Decisive killing + Multiple female protagonists + Don't follow the boat] Just after time travel, Ryan became a five-year-old Celestial Dragon. His father put the weapon into his hand and pointed it at a native of the Valley of the Gods of the same age. "Kill him and complete your first hunt." Before Ryan could make a choice, the sky was torn apart by the overlord color. "The hunting game is over!" Rocks led Whitebeard, Golden Lion, Lingling, and Kaido to fall from the sky. "Now, it's my turn to hunt you!" The Valley of the Gods fell into destruction, and his father died fighting to protect Ryan. In a desperate situation, he broke into the treasure house of prizes, swallowed the bird fruit, phantom beast species, and golden-winged roc form, and was finally rescued from the ruins by Garp. Since then, the Navy has had a monster that shouldn't exist. He does not admire Roger, does not agree with the so-called freedom of pirates, and will not accompany Luffy to re-read the original work. Pirates who harm civilians should be killed! The Navy is corrupt and perverts the law and should be executed! The Celestial Dragons regard all living beings as slaves and deserve to die as well! Years later, the war broke out. Ace was executed on time, Luffy was defeated and arrested, and the two four emperors Whitebeard and Kaido joined forces to attack the Navy headquarters. Ryan is holding a gold-plated phoenix wing to "hold the sea", and the golden wings behind his back cover the sky. "The so-called Yonko are just four larger pirates." "No one can leave alive today!"
